To get that extra glow before beginning the European tour for Friends with Benefits, Mila Kunis treated herself to a $7,000 facial from celebrity aesthetician Scott-Vincent Borba The posh procedure, known as the HD Diamond and Ruby and Diamond Peel, uses tiny precious stones as antioxidants for the skin—and it's not the first time Kunis has splurged on the treatment. Before the Golden Globes in January, the 27-year-old actress also had the peel, which requires sucking on an ice cube to reduce puffiness. "I always do [this on] her skin, neck, décolleté, arms, and the back of her hands," Borba told InStyle at the time. "Anything that will be possibly showing with her dress."

Serena Williams: Evian bath

Though she's more apt to drink a few bottles during a tennis match, back in 2005, Serena Williams became the first guest Miami's Hotel Victor to sample the $5000 Evian Experience. Available to those staying in the $6000-a-night penthouse suite, the procedure features a bath in 1000 liters of Evian spring water and colorful Gerber daisies. "I could feel the difference from the moment I stepped in," Williams said after her chic soak. "The water felt so pure. Also, Evian is a sponsor of the US Open, which I've won the last few years, so I guess you can say the water has been lucky for me."
